The JINR Distributed Computing Environment

The experiments at the Large Hadron Collider (LHC) at CERN (Geneva, Switzerland) played a leading role in scientific research not only in elementary particle physics and nuclear physics, but also in the field of Big Data Analytics. Global distributed system for processing, storage and analyzing data WLCG (Worldwide LHC Computing GRID) brings together the resources of about 180 computer centres in 50 countries, the total storage capacity is more than 1 Exabytes. Data processing and analysis is carried out using high-performance complexes (Grid), academic, national and commercial resources of cloud computing, supercomputers and other resources. JINR is actively involved in the integration of distributed heterogeneous resources and the development of Big data technologies to provide modern megaprojects in such high-intensity fields of science as high energy physics, astrophysics, bioinformatics and others. JINR is actively working on the construction of a unique NICA accelerator complex, which requires new approaches to the implementation of distributed infrastructure for processing and analysis of experimental data. The report provides an overview of major integrated infrastructures to support mega-projects and trends in their evolution. The report also presents the main results of the Laboratory of Information Technologies Joint Institute for Nuclear Research (JINR) in the development of distributed computing. A brief overview of the projects in the field of the development of distributed computations performed by LIT in Russia, CERN, the USA, China, JINR Member States. The analysis works on the integration of technology HPC, grid, cloud, BigData for large international projects.
